Summary
This study presents a 3D CT-guided technique for accurately locating and removing small metal foreign bodies from soft tissues. The minimally invasive method proved effective and safe in eight patients, offering a reliable alternative for foreign body extraction.
Area of Science:
- Medical Imaging
- Surgical Techniques
- Foreign Body Removal
Background:
- Small metal foreign bodies in soft tissues pose diagnostic and removal challenges.
- Existing methods may lack precision or carry risks.
Purpose of the Study:
- To introduce and evaluate a novel 3D CT-guided technique for precise localization and removal of small metallic foreign bodies.
- To assess the accuracy, reliability, and safety of this new approach.
Main Methods:
- A technique using syringe needles as guides under 3D CT guidance was employed in eight patients.
- Needles were inserted around the foreign body entry point, with 3D CT confirming location.
- Dissection followed the path of the closest needle for foreign body extraction.
Main Results:
- Successful removal of eight metallic foreign bodies (slices, nails, fish hook, needlepoint) using the 3D CT-guided technique.
- Procedures were completed with no reported complications.
- Operation times were efficient, ranging from 15 to 25 minutes.
Conclusions:
- The 3D CT-guided technique is an accurate, reliable, and safe method for removing small metallic foreign bodies from soft tissues.
- This technique offers a low risk of complications and is a viable first-choice option for extraction.
